Modules of elasticity are the most important physical quantities, included in the various engineering calculations at the determining of the strength and stability of machine parts and constructions and the natural frequencies of the moving parts of machines and mechanisms. The knowledge of them is necessary for the metallurgical technological calculations. The accuracy of the determining of the values of the elastic modules and their changes due to the influence of various factors is of great interest, since the requirements for the reliability of the metallurgical and engineering products, saving in materials and reducing the weight of constructions have increased. For the investigating of the stress state of the solidifying ingots (without which it is impossible to choose the optimal technological regimes of their production) and the designing of metal equipments, the information about the values of the elastic modules and the rheological behavior of metals and alloys at high temperatures is necessary. The investigations of the influence of various factors, including temperature, on the elastic modules of metals are extremely important. The mechanical properties of metals and alloys (for example, strength, plasticity, toughness, and others) depend on both microstructure (number of phases, their dispersion, distribution, mutual arrangement) and substructure (defects of crystal structure, their density, mobility, interaction with each other and with the atoms of impurities) and are in a certain way connected with the interatomic interactions in metals. Therefore, the correlations between the mechanical properties and the elastic modules of materials are not accidental. In this paper, based on the analysis of experimental data about the dependence of the elastic modulus of elasticity (young modulus) for various steels and alloys, the analytical dependence of the elastic modulus on temperature for the heat-resistant steels and alloys, used in the production of steel sheets and steel pipes of large diameter for main pipelines, is obtained. The results of investigation can be widely used in the metallurgical and machine-building plants.
